"Quantum mechanics is not indeterministic as many people think, it's a completely deterministic theory. It's second order differential equations with boundary conditions and they're completely determined. Once you give the initial conditions the wave function of a particle after some time is completely determined, so there's no indeterminacy. Now what happens when you measure the properties of that particle based on its wave function that's probabilistic."
